Ya know what urks me? When a guy I just met tries to "bond" with me by making lewd comments about women in the vicinity. First of all, how very lame, desperate, and (literally) sophomoric. Secondly, I'm rather gay.
Next time it happens, instead of the please-stop-grunt-and-glare I typically use, I'm going to say, "Totally dude, and check out that humpy paramedic. I'd sure like to ride his ass. Now let's spit and bump chests."
